Answer 2

Given : two numbers are in ratio 8 : 3 and their sum is 143

To find : the number

Solution : Let the number be x

=> 8x : 3x

According to the question

8x + 3x = 143

=> 11x = 143

$\implies \dfrac{ \cancel{143}}{ \cancel{13} }$

$\large{ \boxed {\underline {\underline{=> x = \ {13}} }}}$

$\large\red{ \underline{ \underline{ \mathcal{VERIFICATION}}}}$

To verify it put the value of x

=> 8 * 13 + 3* 13 = 143

=> 104 + 39 = 143

=> 143 = 143

Verified

$\underline { \underline{Hence \: the \: answer \: is \: 13 }}$
